Test T: DTC B2141 - Non-Volatile Memory Configuration Failure

T1 - T2:

Normal Operation
The air bag Electronic Crash Sensor (ECS) module memory must be configured differently for vehicles with different options. This can be done using either the Service Bay Diagnostic System (SBDS) or the scan tool.

The ECS checks the memory option content for the proper configuration.

If the ECS detects an improper configuration, it will store a Diagnostic Trouble Code (DTC) B2141 in memory and flash the air bag indicator five times per second.

Possible Causes
A non-volatile memory configuration failure could be caused by:
^ an improper configuration file used.
^ a damaged or inoperative ECS module.
